The reason in science demonstrations at schools, vinegar and baking soda are used is that when these two ingredients are mixed, carbon dioxide gas is produced very rapidly. This makes the vinegar and anything else mixed in with it froth up and expand. This causes the "eruption" of the volcano.
An alternative approach may be to use diet cola and the mint candy known as "Mentos" as demonstrated on the US Discovery channel program "Mythbusters".
The mentos are covered in lots of small dimples. When a mento is dropped into diet cola, these dimples act as points of nucleation for the dissolved carbon dioxide in the cola meaning that bubbles form at these points. This causes lots of gas to be released very rapidly (just as if you'd shaken up the bottle of cola and taken the lid off).
Apparently the mint flavoured mentos are required for this to work (as they are covered in the tiny dimples whereas other flavours have different coatings which do not have the dimples).
This may be a suitable method of creating your volcanic eruption demonstration.

What can make a chemical reaction with vinegar?
Baking soda or any carbonate.
What is dangerous when mixed with vinegar?
Stupidity and Baking soda can possibly make a bomb.
What will happen if someone mixxes red cabbage in a blender and then added some water and baking soda and vinegar?
You will get a frothy red mess. The baking soda and vinegar will combine to produce carbon dioxide as the acid in the vinegar combines with the base in the baking soda. The red cabbage will will make it colorful, and the water will slow the reaction. On the other hand, red cabbage and vinegar will make a nice pickled cabbage.
How do you make a tidal power model?
you can make a baking soda volcanoes and paint and decorate it for a project
When baking soda and cold vinegar are mixed together does it make a bigger reaction than room temperature vinegar?
no the reaction is not bigger, but it does last longer with cold vinegar.
How do you make volcanoes without making baking soda?
I think use coke not diet and mentos
How do you make a volcano with vinegar?
baking soda and vinegar put the baking soda in first
How do you make baking soda explode?
Baking soda and vinegar!
Which will make the rocket fly higher vinegar or baking soda?
vinegar
How do you make a eruption without using vinegar and baking soda or soda and a Mentos?
open a coke bottle to fast.
Does bubbles occur in cold water when baking soda is added?
No, but it depends on what kind of bubbles you are trying to make. Soap bubbles aren't made out of water and baking soda. You can add baking soda to vinegar and create bubbles, as you've seen in fake volcanoes.
